S. D. WASHBURN.

PAPER DRINKING CUP.

APPLICATION FILED SEPT. 29, 1911.

Patented June 24, 1913.

UNITED STATES. PATENT OFFICE.

SAMUEL D. WASHBURN, OF BOSTON, MASSACHUSETTS.

PAPER DRINKING-CUP.

Specification of Letters Patent.

rammed June 24, 1913.

Application filed September 29, 1911. Serial no. 851,921. 1

To all whom it may concern:

ticularly designed for a drinking cup, and

adapted for temporar and individual use, and of such low cost t at it may be thrown away or destroyed after a single use if desired.

The'cu of this invention is composed of a single lank of paper. of circular or generally circular shape, and maintains its cup shape solely by reason of the disposition and arrangement of the folds of the blank. It thus (presents no joints or seams re uiring the a dition of glue, paste or other oreign matter.

The vertical or side walls of the cup flare upwardly and present a series of symmetrically disposed box plaits, and the entire edge of the cup presents an annular down-turned portion so that the folds of the plaits are ocked and it is impossible to destroy the shape of the cup by releasing the folds without a determined effort, which breaks the paper. This structure of down-turned edge causes the upper rim of the completed cup to present a smooth, even surface, comfortable to the lips of the user.

The dispositionof the paper into folds in the side walls and turned edge gives the cup a very substantial and solid form so that it readily maintains its shape under use, and can be easily handled and placed on a table when empty or when filled with liquid.

The drawings represent the preferred form of the invention where thebody of the the completed cup. Fig. 4

should be of a circular or generally circular shape substantially as shown in Flg. 1, and the radius of this blank must equal the radius of bottom of the cup plus the length of the flaring side wall plus the length of the down-turned edge. The cup may be folded into its completed shape by any suitable means, and I have invented a machine for folding the cup which is made the sub-' j ect of a companion application No. 614,581, filed March 15,1911.

The bottom of the cup is flat and'circular,

or substantiall circular in shape, as indicated at A in ig. 2. From the periphery of the bottom to the edge of the blank a series, herein shown as four, symmetrically disposed box plaits B extend and these are so formed that the sections 0 between the box plaits form the chief portion of the inner-surface of the flaring walls of the cup. The upper edge of the on between the periphery of the blank and the dotted circular line D shown in Fig. 1 is down-turned outwardly and backwardly upon the body of the cup as shown clearl 1n Fig. '3. This causes the rim of the finished cup, which is chiefly formed by the section C, to be perfectly smooth and even, and comfortable to the lips of the user. Furthermore, this out wardly and downwardly folded edge throu h which the box plants are carried as seen rom Figs. 3 and 4, serves to lock the folds 'of the box plaits of the cup and prevents the cu from losing its shape under conditions 0 use, and in effect renders it impossible to destroy the shape of the cup and obliterate the folds except by a determined forceful effort, which will be found to break the paper.

The completed cups readily nest one within the other, and may be packed in that form for shipment if desired.

It will be seen that the cup consists of absolutely nothing but the single unbroken seamless, jointless blank of paper, no paste, glue or foreign matter being necessary, and the cup being maintained in its completedform solely by the relation and disposition of its folds.

The invention having been described, what is claimed as new and desired to be secured by Letters Patent is:

A cup com osed of a single substantially circular blan of paper comprising a flat circnl ei bottom and an upwardly flaring In testimony whereof, I have signed my bod presenting at plufality 6f hex phiits, name td this specification; in the presence sai plaited body at and throughout its of two subscriblng witnesses.
